Title: Rubber composition suitable for automobile tires and its production
Inventor: INUI NAOKI
IPC: C08K5/36
Filed: 1992-05-14
Abstract: ABSTRACT          A styrene/butadiene copolymer rubber to be used for automobile tires is lowered in its rolling resistance by blending it with carbon black and the following components (A) and (B):    (A)  a dinitrodiamine compound represented by the following formula (I):                 (I) wherein X is a divalent organic group such as an alkylene, R1 is hydrogen or an organic group such as an alkyl, provided that two nitrogen atoms linking through X may further link through R1, and R2 and R3 are each hydrogen or an alkyl, provided that R2 and R3 may conjointly form a ring; and (B)  a sulfide compound selected from dibenzothiazyl disulfide, tetralkylthiuram disulfide, and alkyl- or hydroxy-substituted phenol sulfide resin.          The dinitrodiamine compound (A) and the sulfide compound (B) are added simultaneously to the rubber together with the carbon black in a first kneading step of a high temperature.  The resulting rubber composition is lowered in its loss factor (tan 6) at around 60°C as compared with the case where the dinitrodiamine compound (A) is added alone, and it contributes to decrease the rolling resistance of tires made from the rubber composition.

Title: In situ growth of superconducting films
Inventor: JAMES TIMOTHY W
IPC: C01G1/00
Filed: 1991-10-03
Abstract: In situ vapor phase growth of thallium containing superconductors is achieved by controlling thallium volatility. Thallium volatility is controlled by providing active oxygen at the surface of the growing material and by avoiding collisions of energetic species with the growing material. In the preferred embodiment, a thallium containing superconductor is grown by laser ablation of a target, and by provision of oxygen during growth. More specificially, a source of thallium, calcium, barium, copper and oxygen is created by laser ablation of a thallium rich target (20), generating an ablation plume (36) that is directed onto a heated substrate (12) through the oxygen, with the plume passing through oxygen having a pressure from 10-2 to ten torr. Epitaxial superconducting thin films of thallium, calcium, barium, copper and oxygen have been grown by this technique. Various superconducting phases may be engineered through use of this method.

Filed: 1991-09-10
Abstract: 91.013 PCT                 LEYBOLD AKTIENGESELLSCHAFT     ABSTRACT The invention relates to a process for regenerating a cryopump (1) that is equipped with an inlet valve (33), with cold surfaces (6, 8, 11) which have a temperature during operation of the pump that effects the condensation and/or adsorption of gases and which are heated for the purpose of regenerating them, the cryopump further including a backing pump (45) that is connected with the pump interior (9) by way of a valve (44).  In this process, heating of the cold surfaces begins if the inlet valve (33) is closed and the connection between the pump interior (9) and the connected backing pump (45) is blocked so that, in addition to the temperature of the cold surfaces, the pressure in the pump interior also rises to values that lie above the corresponding values of the triple point of the gas to be removed.  The removal of the precipitates released from the cold surfaces is effected in liquid and/or gaseous form through a conduit (46) equipped with a regeneration valve (47) that is actuated as a function of the pressure in the pump interior (9).

Abstract: ABSTRACT OF THE DISCLOSURE The  disclosure  relates   to  the  linear   power amplification, in  a  single channel,  of  a  composite signal formed by two  independent signals. In a  single channel formed by correction means followed by a linear preamplifier followed  by  a saturated  amplifier,  the filtering and  symmetry effect  produced, both  in  the correction means and  in the  amplifier, is  profitably used  to  compensate  for  the  clipping  due  to   the amplifier. This makes it possible to obtain undistorted output signals whose amplitude  exceeds the  level  of saturation of the amplifier. The compensation makes  it necessary  for  the  transfer  characteristic  of   the correction means  to have  a  given slope  between  two points beyond  which  the  saturation  appears in the amplifier and a slope that is substantially thrice  the given  slope  on  each   side  of  these  two   points. Application especially to television.
